****in fact many early radio DJ’s would chain smoke just to keep their “radio voice”.***
Several years ago I was watching some TV show in which the moderator was talking t a guest in the audience.
As I listened I said to my wife...”that man is a professional speaker because his voice is too good and his wording is perfect.”
The moderator then asked the guest..”What line of work do you do?”
The guest said ..” I am a radio announcer.”
Voices are born. Many people don’t realize the power of their speech. Many more should be singing.
